GeForce 930M vs GeForce 9500 GT 1GB GDDR3

Intro

Compare those specifications to the GeForce 9500 GT 1GB GDDR3, which has GPU clock speed of 550 MHz, and 1024 MB of GDDR3 RAM set to run at 800 MHz through a 128-bit bus. It also is made up of 32 Stream Processors, 16 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce 9500 GT 1GB GDDR3 should theoretically be quite a bit better than the GeForce 930M in general. (explain)

GeForce 9500 GT 1GB GDDR3		25600 MB/sec
GeForce 930M		14400 MB/sec
	Difference: 11200 (78%)

Texel Rate

The GeForce 930M should be quite a bit (about 153%) faster with regards to anisotropic filtering than the GeForce 9500 GT 1GB GDDR3. (explain)

GeForce 930M		22272 Mtexels/sec
GeForce 9500 GT 1GB GDDR3		8800 Mtexels/sec
	Difference: 13472 (153%)

Pixel Rate

The GeForce 930M should be a lot (more or less 69%) more effective at FSAA than the GeForce 9500 GT 1GB GDDR3, and should be able to handle higher resolutions while still performing well. (explain)

GeForce 930M		7424 Mpixels/sec
GeForce 9500 GT 1GB GDDR3		4400 Mpixels/sec
	Difference: 3024 (69%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
